If he's got a hand at all, you've got to three-bet the turn. You might get it capped, but at worst he's putting four big bets in (check call the river). There's no guarantee he'll lead or CR on the river after your call on the turn.

That's probably been said by someone else already.

I'm a great believer in hammering the turn, if only for the simple reason it's the only way to possibly get the max number of big bets in the pot. Am I being clear? I mean you can't get eight bets in if you stop at two on the turn. Plus people can be optimistic on the turn, moreso than on the river, since there's always the hope of the miracle card.
